Viral Hepatitis in Somalia: An Updated Critical Review of Epidemiology and Public Health Priorities
This critical review synthesizes heterogeneous data from diverse Somali populations to highlight the urgent need for a coordinated public health response centered on vaccination, safe medical practices, and improved surveillance, while emphasizing that current fragmented studies are insufficient to establish a definitive national prevalence of viral hepatitis.

Viruses that attack the liver are a silent, persistent threat to human health around the world. These infections, known as viral hepatitis, come in several forms, each with its own way of spreading and its own set of consequences. Some travel through contaminated food or water, while others move through blood or from a mother to her baby during birth. When these viruses take hold, they can cause long-term damage, leading to severe scarring of the liver or cancer years later. For decades, global health organizations have worked to stop these infections through vaccines, safe medical practices, and better testing. Yet in places where health systems are fragile or data is scarce, understanding the true scale of the problem remains difficult. Without clear answers, it is hard to know where to direct resources or how to measure if efforts to save lives are actually working.
In Somalia, a nation that has faced decades of instability and limited health infrastructure, the question of how widespread viral hepatitis is has been particularly tricky to answer. A new critical review by researchers at the Riaada Academy seeks to untangle this confusion. Rather than trying to calculate a single, definitive number for how many people in the country are infected, the authors took a different approach. They gathered and examined dozens of existing studies, ranging from historical surveys to recent tests done in hospitals and clinics. Their goal was not to produce a fresh national census, but to make sense of the scattered evidence that already exists and to identify what can be done right now to protect people.
The researchers found that the available data is a patchwork of different stories, each telling the truth about a specific group of people but none representing the entire country. For instance, studies looking at pregnant women in specific hospitals in Mogadishu found that roughly one in ten tested positive for the hepatitis B virus. In contrast, a study of blood donors in the same city showed a slightly lower rate, while tests on patients in a large tertiary hospital showed a much lower number. These differences do not mean the data is wrong; they simply reflect that the people being tested are different. A pregnant woman, a blood donor, and a dialysis patient all face different risks and have different histories. The authors argue that treating any one of these numbers as the national average would be misleading. It would be like trying to guess the average height of all people in a city by measuring only basketball players or only children; the result would be accurate for that specific group but useless for the whole population.
One of the most important findings is that the country has long been considered a high-risk area for these infections, but the old numbers often cited come from decades ago or from very small, specific groups. A major historical review of studies from 1977 to 2016 suggested that nearly one in five people might have been infected with hepatitis B, but the authors of this new paper caution that these figures cannot be applied to Somalia today. The data is too old, and the methods used in the past were not uniform. Similarly, evidence of outbreaks in the past, such as a cluster of hepatitis E cases during a humanitarian crisis in the early 1990s, shows that the virus can spread quickly under certain conditions, but it does not tell us how common it is right now. The researchers emphasize that without a new, carefully designed survey that samples people from all over the country, no one can know the true national prevalence.
Despite the lack of a single national number, the evidence points clearly to where action is needed. The review highlights that preventing the virus from passing from mother to child is a critical priority. In the studies examined, a significant number of pregnant women were found to carry the virus, yet the systems to catch these cases and protect their babies are not fully in place. The researchers stress that every newborn should receive a vaccine dose within the first day of life, a simple step that can stop the virus from taking hold for a lifetime. They also point out that health workers themselves are at risk. Surveys of medical students showed that very few had completed the full course of hepatitis B vaccinations, leaving them vulnerable to infection in their future careers. This gap suggests that training institutions need to do more to protect the people who will be caring for the sick.
The safety of blood supplies and medical injections is another area where the data raises alarms. Studies of blood donors and patients undergoing dialysis showed that a notable percentage carried the virus, underscoring the need for strict screening of every blood donation and safe practices in all medical settings. The authors note that finding someone with the virus is only the first step; the real challenge is ensuring they are linked to care, tested for other related viruses, and offered treatment if needed. Currently, the system is fragmented, with different studies looking at different pieces of the puzzle without connecting them.
The paper concludes that Somalia needs a coordinated plan that focuses on what can be measured and improved right now, rather than waiting for perfect national statistics. This plan should include reliable vaccination for infants, routine testing for pregnant women, safe blood practices, and better protection for health workers. It also calls for a new kind of data collection that tracks progress over time, distinguishing between people who have been screened and those who have been diagnosed and treated. The researchers argue that until the country has a unified way of gathering and sharing this information, it will be impossible to know if efforts to eliminate the disease are succeeding. The path forward is not about finding a single magic number, but about building a system where every person, from a newborn in a rural village to a student in a medical school, is protected from a preventable and deadly disease.
